Abstract
The recently discovered reaction between tri-phenylphosphine-alkylidenes of type I11 (obtained from the bromides I by the sequence shown) and carbonyl compounds to produce the corresponding ethylenes IV, the so-called Wittig reaction, has become one of wide scope and utility in synthetic chemistry. 2 We first became interested in the application of this reaction in the steroid field in
